How do a concave mirror and convex mirror differ?
A concave mirror, or converging mirror, has a reflecting surface that bulges inward (away from the incident light). A convex mirror, fish eye mirror or diverging mirror, is a curved mirror in which the reflective surface bulges toward the light source.
Which type mirror is used a doctors head mirror?
Convex usually, its used as a light source and not as a magnifier (or imager of any sort).
Why are concave mirrors used in flood lights?
In flood lights,the source of light is placed between the pole and focus of a concave mirror so as to obtain a diverging beam of light..

Is a mirror a natural source of light?
A mirror is not a source of light, natural or otherwise.

Why is concave mirror used in street lights?
bcause when light source placed at focus of the mirror, after flashing the light form the source to the mirror after reflection a straight parallel beam of light emerges which makes the street bright

How does light reflect off a convex and concave?
A parallel light source will reflect off a concave mirror and go through a point inside the curve called the focus. Reflecting from a convex mirror will cause all light to bounce off in a straight line away from a focus point behind the mirror.

Why are concave mirrors used in the head light of vehicles?
Concave mirrors are used because they will reflect a light source inside the curve in one general direction. To be more specific, the mirrors are close to parabolic. Parabolas have the property that light beams generated at the focal point of the parabola are all reflected parallel out of the mirror.
What is the Illuminating parts of compound microscope?
A compound microscope can either have a light bulb or a mirror. If yours has a light bulb, turn it on to view your slide. You can't use the light in your room or lab to view your slide, because you will block all that light when you use the microscope. If your microscope has a mirror then you might need a another light source to point at the mirror to view your slide.
How can you focus white light?
You can use a concave or vice-versa round glass object AKA magnifiying glass. Then you have to focus the rays' vectors straight through the center of the magnifiying glass so that it focuses light into a single spot.
Which type of lens magnifies convex or concave?
Convex are thicker in the middle and thin out at the edges. These lenses magnify and are used for reading glasses and to correct long-sightedness (hyperopia). Concave lenses are thin in the middle and thick towards the edges. These lenses shrink things and are used to correct short-sightedness (myopia). A good example of this is to take a spoon and look at your reflection in it. Looking at the concave side of the spoon (the front) will make you look smaller, looking at the convex side of the spoon (the back) will make you look bigger. A concave mirror can magnify. Convex mirrors always shrinks things. They are used sometimes in offside rear vision mirrors for vehicles. A concave mirror will also shrink things if you look at the mirror from far enough away and the object you look at is also far away (but you wouldn't want to use it for a rear vision mirror because it then also turns stuff upside down). Concave lenses disperse light rays outward, rendering it impossible for them to focus incoming light onto a plane surface. Their "focus" is virtual, behind the lens on the side of the light source. If the concave surface is used as a reflector, it will form a real image. This is the basis for reflector telescopes. Further info: http://en.wikipedia.org/wiki/Lens_(optics)
What is the use of concave mirror?
They are used as dentists' mirrrors to magnify the image of a patients teeth to faciliate the examination.They are used as cosmetic mirrors to have an enlarged view of the face to apply make up or to shaveUsed as source of fire.They are useful in projector lamps.They are used in telescopes.headlights of carsreflectors in flash-lights
